You might have luck buying used on eBay, but I don't know about Counter strike. I couldn't even reliably run it 1080p on Intel HD Graphics 530 (i5-6600K). A dedicated GPU would be necessary for gaming.
Is there any system setting or something in Device Manager that tells me if my touchscreen laptop supports a pressure sensitive stylus? Basically if its Wacom or not.
My laptop: ASUS Q524uQ
